Thermal Status GT (THERM_STATUS_GT_0_0_0_MCHBAR_PCU) – Offset 59c0
Contains status information about the processors thermal sensor and automatic thermal monitoring facilities.
Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
31 | 0b | RO/V | (VALID) This bit indicates that the TEMPERATURE field is valid. It is set by PCODE if the temperature is within valid thermal sensor range. |
30:27 | 0001b | RO | (RESOLUTION) Supported resolution in degrees C. |
26:24 | 0h | RO | Reserved |
23:16 | 0h | RO/V | (TEMPERATURE) This is a temperature offset in degrees C below theTJ Max temperature. This number is meaningful only if VALID bit in this register is set. |
15 | 0b | RW/0C/V | Cross Domain Limit Log (CROSS_DOMAIN_LIMIT_LOG) If set (1), indicates another hardware domain (e.g. processor graphics) has limited energy efficiency optimizations in the processor core domain since the last clearing of this bit or a reset. |
14 | 0b | RO/V | Cross Domain Limit Status (CROSS_DOMAIN_LIMIT_STATUS) RO - If set (1), indicates another hardware domain (e.g. processor graphics) is currently limiting energy efficiency optimizations in the processor core domain. |
13 | 0b | RW/0C/V | Current Limit Log (CURRENT_LIMIT_LOG) R/WC0 - If set (1), an electrical current limit has been exceeded that has adversely impacted energy efficiency optimizations since the last clearing of this bit or a reset. This bit is sticky, software may clear this bit by writing a zero (0). |
12 | 0b | RO/V | Current Limit Status (CURRENT_LIMIT_STATUS) RO - If set (1), indicates an electrical current limit (e.g. Electrical Design Point/IccMax) is being exceeded and is adversely impacting energy efficiency optimizations. |
11 | 0b | RW/0C/V | Power Limitation Log (POWER_LIMITATION_LOG) R/WC0 - Sticky bit which indicates whether the current P-state is limited by power limitation since the last clearing of this bit or a reset. |
10 | 0b | RO/V | Power Limitation Status (POWER_LIMITATION_STATUS) RO - Indicates whether the current P-state is limited by power limitation. |
9 | 0b | RW/0C/V | Threshold2 Log (THRESHOLD2_LOG) Sticky log bit that asserts on a 0 to 1 or a 1 to 0 transition of the THRESHOLD2_STATUS bit. |
8 | 0b | RO/V | Threshold2 Status (THRESHOLD2_STATUS) Indicates that the current temperature is higher than or equal to Threshold 2 temperature. |
7 | 0b | RW/0C/V | Threshold1 Log (THRESHOLD1_LOG) Sticky log bit that asserts on a 0 to 1 or a 1 to 0 transition of the THRESHOLD1_STATUS bit. |
6 | 0b | RO/V | Threshold1 Status (THRESHOLD1_STATUS) Indicates that the current temperature is higher than or equal to Threshold 1 temperature. |
5 | 0b | RW/0C/V | Out Of Specification Log (OUT_OF_SPEC_LOG) Sticky log bit indicating that the processor operating out of its thermal specification since the last time this bit was cleared. |
4 | 0b | RO/V | Out Of Specification Status (OUT_OF_SPEC_STATUS) Status bit indicating that the processor is operating out of its thermal specification. Once set, this bit should only clear on a reset. |
3 | 0b | RW/0C/V | PROCHOT# Log (PROCHOT_LOG) Sticky log bit indicating that xxPROCHOT# has been asserted since the last time this bit was cleared by SW. |
2 | 0b | RO/V | PROCHOT# Status (PROCHOT_STATUS) Status bit indicating that xxPROCHOT# is currently being asserted. |
1 | 0b | RW/0C/V | Thermal Monitor Log (THERMAL_MONITOR_LOG) Sticky log bit indicating that the core has seen a thermal monitor event since the last time software cleared this bit. |
0 | 0b | RO/V | Thermal Monitor Status (THERMAL_MONITOR_STATUS) Status bit indicating that the Thermal Monitor has tripped and is currently thermally throttling. |
